Hi to all,
I'm creating a 2D surface in CAD and importing to Gmsh how step file.
I have created a geo file to define a square surrounded the surface. I want to
define CAD surface and square as different things. Meshing this file, Gmsh
create a mesh superposing both surfaces, without connections between this
surfaces.
So, the possible way is to define the 2D surface as a hole of square in the geo
file. However making this Gmsh Crash. When a try to define, in geo file, the
lines of 2D as a surface, Gmsh crash.
If I don't define the surface and use the surface number provided by importing
the step file and try to define this surface as hole in square, the Gmsh crash
too.
I don't know any way to solve this problem. Someone know how to solve this
problems?
I'm using gmsh-2.6.1-Windows in Windows 7.
Thanks,
Hugo Milan.
Follow the geo file:

xmin = General.MinX;xmax = General.MaxX;ymin = General.MinY;ymax =
General.MaxY;zmax = General.MaxZ;
lc = 25;lx = (xmax - xmin)*6;ly = (ymax - ymin)*6;
Point(10001) = { (xmax + xmin)/2 - lx, (ymax + ymin)/2 - ly, 0,
lc};Point(10002) = { (xmax + xmin)/2 + lx, (ymax + ymin)/2 - ly, 0,

Characteristic Length {10001:10004} = lc;
